JOHN S. SPENCER, OF NE\V YORK, N. Y.

EYEG LASSES.

SPECIFICATION forming part of Letters, Patent No. 292,959, dated February 5, 1884.

Application filed May 16, 1883. (No model.) i

To all; whom it may concern.-

Be it known that 1, JOHN S. SrENonR, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Eyeglasses, of which the following is a specification.

The invention has relation to iinprovemcnts in eyeglasses, and especially to that class of eyeglasses in which elastic or yielding nose pieces are employed.

The character of my improvements will be understood from the description hereinafter presented, reference being had to the accompanying drawings, in which Figure l is a view of an eyeglass, showing the construction of the nose-pieces and other parts in position. Fig. 2 is a view of a single glass. Fig. 3 is an enlarged perspective view of one of the nose-pieces, and Fig. 4 is an inverted perspective view of the bridgepiece.

Referring to the drawings,'a (I. represent the nosepieces, the lower ends of which are bowed and secured to pillars or standards attached to the frames 1) or to the glasses. The nosepieces will be of a suitable kind and quality of metal, their upper parts being bent at an angle, and their extreme ends also bent to form shoulders c, the functions of the shoulders being to prevent the escape of the upper end of the nose-pieces from their sockets in the bow-spring. The general shape of the nose-pieces and their position with relation to the glasses are indicated with sufficient certainty in the drawings. The connecting or how spring f is distinctive, in that its ends are bent and provided with sockets, (indicated by the letters (Z (2,) in which the ends of the nose-pieces are introduced, as indicated in Fig. 1, the escape or dislocation of the upper part of the nose-pieces being prevented by the shoulders c, which are held in contact with thesocketed ends by the elasticity of the parts, The bow-spring is attached near its ends to the pillars or supports 6, in the customary manner, the sockets d d in its ends being properly arranged with relation 'to the nose-pieces.

of the nose-pieces are of full retained and have free play,

It is obvious that theinanner of attaching the nose-pieces to the glasses is a matter of judgment, which may be varied according to the character of the frame and other circumstances. No difficulty will be experienced in practicing the invention in connection with tionis materially weakened, and frequently necessitates the employment of heavier metal I than would otherwise be required. By my invention the upper ends of the nose-pieces are not reduced, norare the ends of the bridge slotted. According to my invention the ends Width, and the ends of the bridge carry sockets of proper size to receive the ends of the nose-pieces and A to allow them to have a free movement.

XVhat I claim as my invention, and desire to secure by Letters Patent, is-

The nose-pieces A, having theirlower parts bowed and secured in place, and their upper parts bent toward the glasses and to form the shoulders, said bent part and shoulder being of equal width and strength throughout, in

combination with the bridgepiece, the ends of which areof equal proportions, and have applied thereon the sockets d, in which the unreduced upper ends of the nose-pieces are substantially as set forth.

Signed at New York, in the county of New York and State of New York, this 11th day of May, A. D. 1883.
